These elite light infantrymen are trained in wilderness warfare and
taught to survive in harsh conditions.

Rangers are used for scouting and raiding missions far beyond the skills
of ordinary men. The ranks are mostly drawn from frontiersmen already
hardened to living in the wilderness, as their experience making them ideal
for further training. The wild nature of their environment is reflected in
the unconventional tactics they are taught, and they are given some leeway
where formal army discipline is concerned.

Historically, rangers were employed by the British army and were used in the
hostile environments of North America during the French and Indian War. They
would carry out long distance winter raids using crude snowshoes to travel.
The most famous and revered of all rangers were the "Rogers' Rangers", named
for the commanding officer, Robert Rogers. The traditions of Rogers' Rangers
are carried on today by the US Army Rangers, although the modern unit owes
its existence to the Second World War experience to US troops fighting
alongside British commandos and a reformed force in the Korean War.
